Initially the 1:1 magnetite:TSS dose for March 31 was to be based on an assumed average influent TSS concentration of 250 mg/L, as on March 24, but as local air temperatures finally rose during the last week of March, and the snow cover began to melt, flows in the Airport Parkway sewer system began to increase from clear inflow sources such as home sump pumps.

Effect of Magnetite on Mineral Phase Formation in

high grade magnetite ore by magnetic separation. Mean-while, in an oxidizing atmosphere, magnetite is oxidized into hematite. This reaction is an exothermic reaction, so that this reaction heat can be used in place of coke energy. Hence, as a result, the CO 2 emission can be also decreased. The reaction is shown below: 21Fe 34OO˜˚/.23 22 Fe OH

Global Drivers for High Grade Concentrate

Magnetite has low external fuel requirements during induration as it is exothermic, releasing latent energy in the form of heat as it oxidises. This quality reduces the production costs, increases productivity, improves competitiveness and leaves a smaller environmental footprint for steelmakers. Exothermic vs
